RIVET STRING 1 Fild Feb. 2;.- 194s V F1 1. Fig-1213 .2; 34 m ES'PATENT RIVET STRING Louis Frank, Fellows, Calif., assignor of one-third and connect a plurality of rivets in string or rod form, so as to greatly expeditethe work attending the handling of the rivets, particularly the driving and'setting of the same inthe work.

A furtherobject of my invention is to arrange and connect rivets so that the same may be conveniently handled by an appliance such asa rivet gun, which operates rapidly? and accurately in driving; severing and setting the rivets, thereby eifecting'a material savingof time, labor and consequent expense in rivet setting operations.

A further object of my invention is, to directly connect the end of the shank of one rivet to the head of the next adjacent rivet by means of a short neck of small diameter and to form in said neck a circumferential groove, for the accommo! dation and to facilitate the action of the severing mechanism of the rivet gun.

With the foregoing and other objects in View,

my invention consists in certain novel features of construction and arrangement of parts that will be hereinafter more'fully described and claimed and illustratedin the accompanying drawing in which:

Fig. 1 is a side elevational view of a string or series of rivets assembled and connected in accordance with my invention.

V toAdolph Reader, Taft, Calif. r. :lApplication February 22, 1943,;Serial No. 476,742 v H =1Claim. (C l.85-37) yM y invention relates to string rivets; i. e., a series of axially aligned connected rivets and the principal object of my invention is, to arrange Fig. 9 is a cross section takenon the line 9-9 of Fig. 8. j Fig. 10 is an elevational view of apair of'c'onnected rivets having shanks that aresquare cross section.

Fig. 12 is an elevational viewpartly in section and showing the connection between the ends: of the rivet strings. q wi i l i Fig. 13 is a detail sectional view showing one l of the end rivets of a string set in the work:

\Fig. 14is an elevational view of a portion of a string of screws assembled and connected in accordance with my invention. 1

Referring by numerals to the accompanying drawing and particularly to the construction illustrated in Figs. 1, l2 and 13,10, i l] designates the shank or body portions of rivets having flat, heads I I, said rivets being arranged end to end in axial alignment, with the end of the shank of each rivet connected to the center of thehead of-the next adjacent rivet by an axially disposed short neck [2 of small'diameter.

The string of rivets thus formed is capable of being expeditiously driven and set by a rivet gun inasmuch as the handling of the individual rivets is entirely eliminated.

In order to connect the ends of the strings so that same will feed continuouslythrough the rivet guns, a small axially disposed pin it is formed on the end of the shank of the rivet at.

Fig. 2 is an elevational view of a portion of a rivet string made up of a series of flat headed rivets.

Fig.3 is an enlargedcross section taken on the line 3--3 of Fig. 2.

Fig. 4 is an elevational view of aplurality of connected round headed rivets.

Fig. 5' is an elevational view partly in section of a pair, of connected rivets having concave heads.

Fig. 6 is an elevational view of a portion of a string made up of rivets having conical heads.

Fig. 7 is an elevational view of a portion of a string composed of rivets having truncated conical heads.

Fig. 8 is an elevational View partly in section ing tubular shanks.

one end of the string and for the accommodation of the severing means, of the rivet gun, a small circumferential groove is formed in the pin adjacent the end of the shank.

Formed in the head of the rivet atthe opposite end of-the string, is an axial recess III for the reception of that portion of the pin Ill beyond the groove Ill and thus the strings of rivets may be connected prior to their delivery to the rivet gun or setting implement, so as to enable the driving and setting functions to be carried on continuously.

When the last rivet of each string is drivenand set in the work, the severed end of the pin HI re mains in the recess I l and is retained therein by the edge of the metal in the head that is riveted inward over the end of said pin, during thehammering action of the rivet gun (see Fig. 13).

It is to be understood that the necks l2 in the form of string illustrated in Fig. 1 may, if desired, be formed with circumferential grooves such as It", for the accommodation of the severing means of the rivet gun.

OFFICE} In Figs. 2 and 3 the rivet shanks I3 are provided with flat heads I4 and each shank is connected to the head of the next adjacent rivet by a small short axially disposed neck I5.

In Fig. 4 the rivets comprising shanks l6 and round heads II are connectedby short axially disposed necks 18.

In Fig. 5 the rivets composed of shanks l9 and heads 20 having concave outer faces 20 are connected by short axially disposed necks 2|.

In Fig. 6, the rivet shanks 22 are provided with conical heads 23 and are connected by short axially disposed necks 24.

In Fig. 7 the rivets comprising shanks 2'6 and truncated conical heads 21, are connected by short necks 28.

In Figs. 8 and 9 the rivets have tubular shanks 25 with roundedheads 26 and connecting the'end' or at any distance away from said end. Further, said groove may be formedon the necks 2'| ofthe v tubular rivets.

Thus it will be seen that I have provided -rivet strings which are simple in construction, inexpensive of'manufacture andvery effective in performing the functions for which they are intended, viz., the rapid and convenient handling of rivets while the same are being driven and set with arivet gun 'or similar implement.

It will be understood that minor changes in the size,-form and construction of the various parts of my improved rivet strings may be made and substituted for those herein shown and described of each shank with the head of the next adjacent rivet are one or more short necks 21. a

In rivets H) and. II the rivet shanks 29 are square or non-circular in cross section with fiat heads -30 and a short neck 3| connecting the end of each shank with the head of the next adjacent rivet.

shank 32 of each screw connected to the center of the head 3 3 of the next adjacent screw, and the same connection may'be utilized between nails, tacks and the like.

Groove I 0' may be located on neck I: at the .point where same joins the end of the rivet shank In -14 Iyhave shown a string of screws arranged end to end with the end of the threaded ing recess formed in the head of the rivet at the other end of the string the length of which recess is greater than the length of that portion of the pin beyond the groove, so that said portion will be wholly embedded in the rivet head when said portion issevered from the remaining portion of the pin and the rivet is set.
